Great product. Could improve by making frame and some adaptor rings fit in pouch.

Very nicely packaged, does the job, but a little tricky to affix, until you get the hang of it. Not a straightforward fit
Shame, otherwise would be 5 *

Great deal working perfect and nice quality
Easy to use

The gray filter comes in a sturdy protective case and fits exactly into my Rollei rectangular filter holder. The optical properties do not reveal any errors. A satisfied customer thanks you.

I found the set very useful for giving a class on long exposures. The multiple rings allowed me to put the filter onto the range of lenses the students brought. The packaging and quality of the filter and holder is excellent. The attached photograph shows the River Thames blurred at Richmond Lock - some slight cloud motion there too.

A few years ago, I started beefing up my camera equipment. I had a Canon 5D Mark IV camera body, but didn’t have great glass. So, I started my gear journey by upgrading my lenses. I now have four amazing lenses including a 70-200, 24-70, 100mm Macro, and a Wide Angle lens. After I finalized my collection of lenses, I started looking at accessories I needed to accompany those lenses and came up with a short list of items that included high-quality filters. The problem I had was that I needed to be able have filters that works with all my lenses. Buying filters for each one of your lenses can get really cost prohibitive. So, one solution I found was to get a square filter with step-down rings. K&F Concept has a great option for this type of set-up so I gave it a try.

About a month ago, I shot photos at a wedding on a mountaintop in Tennessee. It was in the middle of the afternoon and the sun was super bright at the location of the ceremony. The venue was huge and I wanted to pack my camera bag somewhat light so that I didn’t have to struggle with tons of equipment. The square filter set from K&F concept was perfect for this type of work. The kit is lightweight and it makes it possible to use the one filter for several different sizes of lenses. During this wedding I was working with an 82mm lens and a 77mm lens as my primary glass. At the ceremony site, I had to quickly swap lenses and reapply the filter in order to get the shots the couple wanted. I found gaps in the ceremony where I could quietly and quickly change lenses and attach the filters without disturbing the event. It worked perfectly and even though some people might consider it cumbersome, I thought it was a lot easier than having to swap lenses and then screw filter into each lens.

When using these filters, I shot exclusively in RAW, but did not perceive any color cast from the filters. The mount is solid and the filter is well-protected by the soft lining in the case. It’s very easy to attach the mount to the lenses and in my opinion is actually easier to work with than individual filters.

I do feel like the lens adapter could fit a little more snuggly onto the camera lens, but I’m definitely not complaining about that and it is certainly not a dealbreaker. It’s just a tweak that could make the product even better than it already is.

One of the most appealing features of this product is its price. At £100, it’s much more budget-friendly than purchasing a single ND1000 filter. This is a great set-up for beginners and professionals alike.

Delivery was very fast. Unbeatable for the price... Everything is processed to a high standard. I can't confirm some criticism that the graduated filter is less foggy towards the middle. It was done very cleanly in my case. If the insertion should be a little difficult, then loosen the 4 screws on the filter holder a little bit and everything runs like butter! No colour cast on the filters! Great bags included... Polarising filter story, just screw an existing one onto the lens and then the filter holder on top. What more could you want without having to spend 400-500€? Full marks from me.

Having some experience with ND filters, I always worry about purple corners or dark spots. I took the set out today and got no strange colors. I love this set, it mounts nicely to my lenses with no fear of it falling off. The picture was taken at 11mm, 13 seconds shutter on my Canon 50D, I found K&F Concept when I wanted a good tripod which I found from them. Now if i need any accessories for my photography i look to them first.

Great value. Filters fit snug and don’t let any light around them. Filters come in a quality case.

I've been looking at a filter set for a while and the price and quality of this set was very appealing, the quality is top notch and definitely comparable to the more expensive filter sets
